Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
As shown in fig. 2, the present embodiment provides an adjustable fixing frame for controlling the force of a heating furnace tube, and the fixing frame includes a clamping portion and a supporting portion.
The clamping part is arranged on the supporting part and used for clamping and fixing the heating furnace pipeline; the supporting part has the function of height adjustment, and can adjust the mounting height of the fixing frame.
Specifically, in this embodiment, the fixed heating furnace pipeline of mode centre gripping that the clamping part adopted "whole saddle board in below + two pipe clamps in top" specifically includes saddle board and two pipe clamps, and the left and right sides in the saddle board upper end is installed respectively to two pipe clamps, and saddle board overall structure is the arc, makes it can paste the outer wall tightly at the heating furnace pipeline, and two pipe clamps of cooperation are fixed the heating furnace pipeline on the saddle board.
Wherein, two pipe clamps pass through the connecting plate to be installed on the saddle board, install the bolt on the connecting plate, through the bolt-up, the mode of bolted connection is convenient for more dismantle the installation.
In particular, in the present embodiment, the support part comprises in particular a support plate and a height adjustment device. The saddle plate is arranged on the supporting plate, a small hole is formed in the middle of one side, in contact with the supporting plate, of the saddle plate, a fixed stop block is arranged at the position corresponding to the supporting plate, the fixed stop block is matched with the small hole in the saddle plate, and the saddle plate on the supporting plate is fixed.
Specifically, in this embodiment, height adjusting device adopts the mode of inside and outside sleeve, specifically includes inner tube and outer tube, and the inner tube cover is in the outer tube, and the clearance between the inside and outside pipe is 2mm, the height-adjusting of being convenient for.
The backup pad passes through the connecting plate to be installed in the upper end of inner tube, is provided with the bolt on the connecting plate, through the bolt-up.
The inner pipe and the outer pipe are both steel pipes and have corresponding rigidity. The outer wall of the inner pipe is equally provided with 3 bearing stop blocks at the same horizontal position, and the bearing stop blocks can stop in the process of downward regulation of the stress of the inner pipe, so that the effect of bearing is achieved.
Fig. 2 shows the analysis of the overall stress of the heating furnace pipeline, and this embodiment includes 2 heating furnaces, and the overall stress of the heating furnace pipeline is analyzed, so that the height H of the fixing frame to be adjusted downward can be calculated, and the installation positions of 3 bearing stoppers can be determined.
The bottom of outer tube is provided with installation PMKD, guarantees that whole mount can stabilize subaerial.
After the heating furnace pipeline is fixedly clamped by the fixing frame, the heating furnace pipeline starts to operate, the pipeline becomes heavy to enable the fixing frame to move downwards, and when the downward movement height is H, the bearing stop block is supported on the outer pipe to enable the heating furnace pipeline not to move downwards any more, as shown in figure 3.
Two specific examples of implementation are provided below.
Examples 1
1. The height H of the adjustable fixing frame to be adjusted downwards is analyzed and calculated according to the method shown in fig. 2. The analytical calculations should include a complete system of connections to the pipeline, i.e. including: in fig. 2, adjustable fixing frames 1 and 2, in-furnace pipelines and supporting structures 3 and 4, external pipelines 5, 6 and 7 and external connecting equipment 8 are arranged;
2. according to the above calculation results, 3 load-bearing blocks 20 are welded on the inner tube 16 in fig. 1, and the 3 load-bearing blocks are equally distributed along the outer wall of the inner sleeve (the included angle of each 2 load-bearing blocks is 120 °) and are at the same height. Wherein H is the height of the adjustable fixing frame which is adjusted downwards.
When the heating furnace pipeline system operates, the pipeline at the pipe frame is displaced downwards, and when the adjustable fixing frame is displaced downwards H, the bearing stop block 20 automatically supports on the outer sleeve 17, so that the pipeline is not displaced downwards at the position.
When the device is stopped and the heating furnace pipeline system stops running, the temperature of the pipeline returns to normal temperature, the heating furnace pipeline system returns to the original position, the pipeline at the position can move upwards, and the adjustable fixing frame does not prevent the pipeline from moving upwards due to the resilience.
EXAMPLES example 2
When the trend of the external pipeline is complex and the pipeline can generate larger horizontal rotation, the pipeline and the structure in the furnace are not well stressed, and the transmission of rotation displacement and even damage are caused. In order to control the horizontal rotation of the external pipe, two identical adjusting and fixing frames can be used in combination, see fig. 4 below. In fig. 4, the larger the distance L between the two fixing frames is, the better the effect of controlling the horizontal rotation of the pipeline is, and the distance L can be determined according to the installation space of the actual situation, and generally L > is 1500 mm. The implementation method of fig. 4 more effectively plays a role of adjusting and fixing the pipe frame, fully controls the pipeline force and moment, and ensures the safe operation of the whole system.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
